SDN Members don't see this ad. (About Ads) 55 year old woman post Chloecystectomy reports of chest pain psl/7 EKG ran. No history of heart problems. Doc I am shadowing told pt that her EKG's didn't come back matching... pt asked me what that meant and i wasn't sure how to answer question. Would that mean that the pt has an irregular heart beat? What would cause that in a pt with no history? Please someone can you help me?
